Cashier: "Oh, you're making spaghetti tonight!"
Cashier: "It must be your turn to cook." *looks at boyfriend*
Boyfriend: *frowns a little*
Cashier: "Don't worry, spaghetti is really hard to mess up!"
Boyfriend/Me: *look at her incredulously*
Cashier: "It's okay, I'm bad at cooking too!" *finishes and hands him the receipt* "Good luck!"
We were both too stunned to say anything, but now I really wish I had defended him somehow and made her look like an idiot. :/
